SPRING-HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 425,997, dated April22, 1890.

Application filed August 13,1889.

T0 aZZ whom it may concern:

Be it known that we, CHARLES II. ECOLES- TON, of Oxford, and GEORGE II.HEBBARD, of Sherburne, in the county of Ghenango and State of New York,have invented a new and useful Improvement in Spring-Holders; and we dohereby declare that the following is a full, clear, and exactdescription of the same.

Our invention is a holding-bracket for spiral springs,'and while we havespecially designed the same for use with rocking-chairs and haveillustrated the invention as applied in this connection, it will beunderstood that it maybe used in other situations with equally goodeffect.

Our objects are to provide means for holding and connecting a spiralspring to the part desired to be placed under tension, which will notrequire any special formation of the spring other than. spiral, .andwill not necessitate screw-threading or crooking the end of the wire.

Further, our object is to furnish a means for holding the spring whichwill permit quick and easy detachment of the spring and the parts heldthereby without removing screws or the su pporting-bracket, and whichwill also permit adjustment to properly align the parts or to place adifferent tension thereupon.

ith these ends in view the invention consists, essentially, of a brackethaving a socket to receive a coil of the spring and adapted to receiveholding pin, which retains said coil therein.

In the drawings, Figure l is a side elevation of the rocker of arocking-chair and the base upon which it rests,with thespring-connection in place. Fig. 2 is a transverse section of the same.Fig. 3 is a perspective view of the bracket and part of the spring, andFig. 4 a longitudinal sectional view of the same.

In the drawings, Ais the rocker; B, the base upon which it rests andmoves; C, the spiral spring extending between these parts, and D D thebrackets, which connect the ends of the springs with the rocker and baseB, respectively. The brackets consist of a baseplate d, having screwholes for attachment to the parts and a rectangular extension 6 off atone edge intended to receive and support one Serial No. 320,594. (Nomodel.)

of the coils of the spring, and while it may be variously adapted forthis purpose we prefer to make the extension with a socket f, which isformed with curved bearing-surfaces f, to receive the coil. The edges ofthe socket embrace the coil and hold it securely against displacement inthe direction of its length. The extension is connected with thebaseplate at its ends only, and this leaves a central opening 9, and asthe bottom of the socket is formed with an opening 2 at its central partthe coil of wire when in place will have an exposed portion 3, extendingthrough be yond the bottom of the socket, and for the purpose ofcompleting the securing of the coil a pin 4, preferably headed andwedgeshaped, is inserted between the exposed part of the coil and theedges of the socket, which are notched at 5. This wedge prevents outwardand circumferential displacement of the coil and provides a rigiddetachable connection. It will be noticed that any ordinary spiralspring can be used with this holding device, the coil itself beingutilized to form the connection instead of threaded ends adapted toreceive nuts or hooked ends. The spring can be easily detached and theparts disconnected for packing or storage by with drawing the wedge, andthis connection allows the adj u stmentof the spring circumferentiallyin cases where through improper placing of the brackets acircumferential tension is created and the rocker and base forced out ofalignment thereby, this being effected, of course, without removing thebracket. By removing the wedge also the tension of the spring can beincreased by stretching it and bringing another coil in connection withthe socket, or the reverse adjustment may be as readily effected. Thebrackets can be used with either side up, and thus they are adapted tosmall or narrow rockers and bases.

It will be obvious that the bracket may be used in other situations thanthat described above, as between the standard and the seat of atilting-chair.

Ve claim- 1. In combination, the spring, the bracket having a baseportion, and a horizontal hearing portion for the spring-coil, saidbearing IOG portion having a vertical opening formed therein, and aremovable pin inserted in said opening, extending transversely acrossthe coil and retained by its frictional contact with the coil and thewall of the opening.

2. In combination, the spring, the bracket consisting of the base, and asocket portion extending therefrom and adapted to receive the coil, saidsocket having an opening through its upper and lower Walls, and a pinextending transversely through the socket and through said openings andtransversely across the contained coil, substantially as described.

3. In combination, the spring, the bracket consisting of the base, and asocket portion extending therefrom adapted to receive the coil, saidsocket having a bottom opening through which the coil projects, andopenings through the walls, and a removable-pin inserted through theopenings in the Walls and bearing upon the projecting or exposed part ofthe coil, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing Witnesses.
